Abstract : This report describes the experimental and basic theoretical work that was performed for the evaluation of a jet generator simulator for a Chemical Oxygen Iodine Laser (COIL) system. Chlorine gas reacts with liquid Basic Hydrogen Peroxide (BHP) in the generator to produce excited oxygen, O2(1 delta). The jet generator for a chemical oxygen iodine laser system has to provide a large reaction surface. This is accomplished in the generator by providing many small orifices through which the liquid BHP will flow and form liquid jets. The liquid jets should be as long and stable as possible to provide a maximum reaction surface. This experiment deals with a finite set of orifice diameters and lengths which allow for convenient scalability procedures in the future.
